■ BOLTING
The body-cover bolting conforms with ANSI B.1.1 The nuts are manufactured to conform with ANSI B18.2.2 Strain-hardened austentic stainless steel
■ COVER
Austenitic stainless steel used for bodies and bonnets offer excellent impact strength, minimize heat loss and protect against corrosion.
■ HINGE PIN
The hinge pin is insrted into the valve and held in position by plug. The larger size valves are provided with bolted flanges instead of plugs.
■ ARM
The arm material is identical to the body. Hinge bushing is provided in the larger valve sizes to minimize friction and eliminate seizing.
■ SEAT RING
The bottom seated type seat ring is screwed into the body. The seating surface is finished by lapping. The forged seat ring is heat-treated to deliver the best mechanical properties and required hardness.
■ DISC
The disc has a sufficient seating surface area which is ground and lapped to a mirror finish. It is of one-piece construction and is heat treated to deliver the required mechanical properties and hardness.
Stellite 6 for all medium and high pressure application prevents seizing and galling
■ BODY
Austenitic stainless steel used for bodies and bonnets offer excellent impact strength, minimize heat loss and protect against corrosion
